It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1 to 4, a back-discharge type siphon toilet according to an embodiment of the present invention includes a toilet body 10, the toilet body 10 includes a toilet bowl 11 and a back-discharge type sewage pipe 12 capable of forming siphon, and an outlet 122 of the back-discharge type sewage pipe is located at the back of the toilet and opened towards the back. The bottom of the bedpan 11 is formed with a water seal 111, and the side wall of the bottom of the bedpan is provided with an injection hole 112 below the water level of the water seal 111. The inlet 121 of the back-drainage type sewage draining pipe is communicated with the water seal 111 and is positioned below the water level of the water seal 111, and the jet hole 112 is arranged opposite to the inlet 121 of the back-drainage type sewage draining pipe. The water-saving device also comprises a flow-increasing water tank 20 and an injection pump 30, wherein the flow-increasing water tank 20 is communicated with the water seal through an injection hole 112, and the injection pump 30 is arranged in the flow-increasing water tank 20. The jet pump 30 is connected to a pressure water source (not shown, such as a tap water pipe) for providing pressure water, and when the pressure water source provides pressure water to the jet pump 30, the water in the flow-increasing water tank 20 is sprayed to the inlet 121 of the back-discharge type sewage pipe through the spray hole 112 together with the pressure water under the action of the jet pump 30, so that the back-discharge type sewage pipe 12 performs siphon sewage discharge. The jet pump 30 and the flow-increasing water tank 20 are matched to play a role in increasing pressure and flow, so that the siphon sewage discharge capability of the back-discharge type siphon toilet can be greatly improved, and the structure is simple and reliable.
In this embodiment, the rear cavity wall of the flow-increasing water tank 20 is provided with a mounting hole 21, the rear end of the injection pump 30 is fixedly mounted in the mounting hole 21, and the front end of the injection pump 30 is fixedly mounted in the injection hole 112, so that the injection pump 30 is positioned front and back, and compared with the case that only the rear end of the injection pump 30 is fixedly mounted in the mounting hole 21, the injection angle of the injection pump 30 can be kept stable, and the injection effect is better.
Preferably, in this embodiment, the front end of the jet pump 30 is in sealing fit with the jet hole 112, so that the dirt in the water seal 111 can be prevented or greatly reduced from entering the flow-increasing water tank 20, and when the jet is performed, the water in the flow-increasing water tank 20 is basically sprayed out from the outlet of the jet pump 30, and cannot run off between the outer wall of the jet pump 30 and the inner wall of the jet hole 112, so that the jet effect is better. In other embodiments, a small gap between the outer wall of the front end of the jet pump 30 and the inner wall of the jet hole 112, which is less than or equal to 2mm, can also achieve the above-mentioned effects, but the effect is slightly worse than the sealing fit. In this embodiment, the outer wall of the front end of the jet pump 30 is in sealing engagement with the inner wall of the jet hole 112 via the corrugated packing 50.
Referring to fig. 3, in the present embodiment, the jet pump 30 is provided with a jet passage 31 and a flow increasing passage 32, a cross-sectional area of an inlet end of the flow increasing passage 32 is larger than a cross-sectional area of an outlet end of the jet passage 31, the jet passage 31 is communicated with a pressure water source for providing pressure water, the water at the outlet end of the jet passage 31 is sprayed toward the inlet end of the flow increasing passage 32, a flow increasing gap 33 communicated with the flow increasing water tank 20 is formed between the outlet end of the jet passage 31 and the inlet end of the flow increasing passage 32, and the water of the flow increasing passage 32 is sprayed toward an inlet 121 of the rear-discharge sewage pipe through the spray hole 112. The operating principle of the jet pump 30 is: when the outlet end of the injection passage 31 injects the pressure water against the inlet end of the flow-increasing passage 32, the water in the flow-increasing water tank 20 can enter the flow-increasing passage 32 via the flow-increasing gap 33 due to the venturi effect, and is finally ejected from the outlet of the flow-increasing passage 32 together with the pressure water. The principle of the ejector pump 30 is common knowledge and will not be described here.
Referring to fig. 2, in the present embodiment, the rear drainage sewage pipe 12 has an inverted V-shaped pipe section, and a highest point position a of a bottom wall of the inverted V-shaped pipe section is higher than a highest point position b of an inlet 121 of the rear drainage sewage pipe. Of course, the inverted V-shaped pipe section can be replaced by an inverted U-shaped pipe section, and the effect is the same.
Referring to fig. 4, in the present embodiment, the flow-increasing water tank 20 is provided with an air outlet 22, the air outlet 22 is communicated with one end of an air outlet pipe 40, the other end of the air outlet pipe 40 is communicated with the outside atmosphere, and a trap 41 is formed on the air outlet pipe 40. By providing the trap 41, the odor in the flow-increasing water tank 20 can be prevented from flowing into the room, and the indoor air quality can be prevented from being affected.
In this embodiment, the rear discharge type siphon toilet is not provided with a water tank having a working water level higher than the water seal water level. For cleaning the inner wall of the toilet bowl 11, the inner wall of the toilet bowl 11 may be washed by supplying water to the upper portion of the toilet bowl 11 through another washing water path using tap water. After the flushing is finished, the other flushing waterway supplements the water to the water seal 111 of the toilet bowl 11, and the water flowing to the water seal 111 flows into the flow-increasing water tank 20 through the injection holes 112 to fill the flow-increasing water tank 20 until the water level of the flow-increasing water tank 20 is flush with the water level of the water seal 111, so as to prepare for the next flushing. The flow-increasing water tank 20 can be integrally formed with the base 10 or fixedly connected after being formed separately.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: it is to be understood that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof, but such modifications or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
